locking actual physical camera settings

Hi everyone! This is first post, sorry if i sound too much like a newb.:)

I was just wondering if there is a script that makes the VrayPhysicalCamera behave like an actual physical camera, warts and all? im studying photography at the moment, and what i mean is real cameras have discrete (albeit customizable) f-stops, shutterspeeds and iso's..

so what im saying is, i think if the rollout settings on the vrayphysicalcam can somehow be locked (if you want to) to go from, say, f/1.4 -> 2.0 -> 2.8 and shutterspeeds at 1/8 -> 1/15 -> 1/30 sec., etc.

while this might seem limiting, it has its merits:
1. it makes sense to someone who is used to using an slr, and gives you a real feel (from experience) if your environment lighting are in a real range, and not physically impossible(?)
2. those that havent used a camera will have an idea of how light is actually controlled in photography (halving and doubling of aperture opening area, shutterspeed, etc)
3. it makes the vrayphysicalcamera feel more "real", maybe even import settings for a real camera body, like a d700:) and of course you can unlock it as you wish.

sorry if it took too long to explain! not a scripter, but im sure its easy enough to do, hehe.. tried to look.. maybe a similar one has been done?

thanks!

Thanks for the reply. No,

Thanks for the reply. No, what i was thinking was actually simpler: just that the values in the vrayphysicalcamera rollouts have specific allowed values for the f-number, ISO and shutterspeed.

basically,for example, you can only choose as values for shutterspeeds(similar to a "typical" slr): 1, 1/2, 1/4, 1/8, 1/15, 1/30, 1/60, 1/125, 1/250, 1/500, 1/1000, etc. that is, you cant choose "1/253.7" sec. Same for ISO (typically 100, 125, 165, 200.. etc)

it's limiting, but this is somewhat more like how a real camera works right?

Thats all really. The f-number, ISo and sspeed can still be set independent of each other of course.:D

thanks for the script! it doesnt do what i was asking for, but it actually has more practical functionality.:)

Alright then. Send me the

Alright then. Send me the list of all values that you want to use for the f-number,shutterspeed and ISO.

Awesome man! Ok took this from my camera (nikon d7000) with a 50mm prime lens:
Aperture: 1.4/1.8/ 2/ 2.2/ 2.5/ 2.8/ 3.2/ 3.5/ 4/ 4.5/ 5/ 5.6/ 6.3/ 7.1/ 8/ 9/ 10/ 11/ 13/ 14/ 16/ 18/ 20/22
Iso: 100/ 125/ 160/ 200/ 250/ 320/ 400/ 500/ 640/ 800/ 1000/ 1250/ 1600/ 2000/ 2500/ 3200/ 4000/ 5000/ 6400
Shutterspeed: (>= 1 sec) 30/ 25/ 20/ 15/ 13/ 10/ 8/ 6/ 5/ 4/ 3/ 2.5/ 2/ 1.6/ 1.3/1 sec
(<1 sec) 1.3/ 1.6/ 2/ 2.5/ 3/ 4/ 5/ 6/ 8/ 10/ 13/ 15/ 20/ 25/ 30/ 40/ 50/ 60/ 80/ 100/ 125/ 160/ 200/ 250/ 320/ 400/ 500/ 640/ 800/ 1000/ 1250/ 1600/ 2000/ 2500/ 3200/ 4000/ 5000/ 6400/ 8000

I can not believe that you doubted in this forum.

Also will be nice to post

Also will be nice to post most used combinations of f-stop,shutterspeed and ISO parameters for some cool presets. I mean something like "Sunny 16 rule" (f/16,1/200,200) etc.
